BGTTLE-FILLING MACHINE.

Specification of Letters Patent. Patented J une 20, 1911,`

Application filed November 27, 1907. Serial No. 404,028.

\ To all whom it may con-cern:

lie it known that l*` linnn ll.. Pannen, a citizen vot the United States, residing at Evanston, in the county oi" took and State a of Illinois, have invented a new and useful Improven'ientl` in Bottle-Filling Machines, ot' which the following` .is a spceitieation.

My invention relates to animprovement' -i n machines-for automatically filling bottles l or other varieties of package with material in liquid or semi-liquid t'orm; my primary ohjeetlieing to provide a novel construction of'pneumatieally-operated machine of the rcharacter referred to that will'adapt. it to measure into the. package a definite quan titty oi the material.

In the'accompanying drawings, Figure l is a broken view showing,r the tilling-nnu-.hine in frontelevation.and also showing the sup- 2O ply-reservoir for the material and its connections with the machine; Fig. 2 a similar view showingr the machine. more complctel \Y and on a larger scale than that observed in Fig'. 1; Fig. 3, a broken view of 25., the machine in side elevation; Fig. t. a broken enlarged view in sectional elevation of a measuring` and fillingr cylinder of thc machine withits admission and discharge cont-rolling valve; Figs. 5, G and 7 are enlai-ged sections taken, respectively, at. the

lines 5, 6 and 7 on Fig. 4 and viewed as indicated by arrows, and Fig. 8 is an enlarged section taken at the line S on Fig. 7 and Viewed `in .the direction of the arrow.

I'have'more immediately devised my .im-

proved machine for lling,r bottles with liquid (especially medical preparations) and therefore hereinafter described it as applied to that purpose. The base of the machine is a rectangular horizontal frame 9, formed preferably of light bar-metal and suitably braced, with a similarly formed rigid' upright rectangular frame 10 o n 'the rearportion of the main or baseframe.

While the machine -is used for filling simultaneously a plurality ofbottles of'uniformor varyingsizes and capacities in a row, it is also, 4of: course, capable ofvv use for filling a single-bottle. j

In similar bearings 11- depending, near 'the front' of the uprightframe 10, from the siderails of the frame 9, is journaled a rock-shaft- 12 carrying a handle 13 onone end which also carries an. arm 14 provided on its outer end with an adjustable stop lito engagel with the base of the adjacent sidesr'al for y limitingl the throw of the rock-shaft.

this rock-shaft. are also carriednear the ini v a ,bottle-filled tray is imposed on the top Jof.

the frame 9 it may be placed with the front row of bottles registering at their necks'with c the depending fill1ng-tubes, 'hereinafter described, and \\"ith.t-he'rack's engaging-at their t'm-wardmost teeth with the dogs l't: Thus, i

when one row of the bottles-has heeniilled one step backward to bring the nextl row vof,

.y l by turning the rock-shaft backwardly the dogs engaging the rackswill move. thertrayiA bottles with their necks in aline1nent\vith.. the filling-tubes, and so on until 'allthe row-s .Y

of bottles have been filled, the `rack-teeth-be- 1 ing spaced apart. with reference to positioninygr the bottle-necks in the'su'ecessive rows relative to the filling'tubes..

To the backs of the side-members of the upright frame l() isfastenedla rectangular' cast frame 101, from neary opposite endsof.-

the lower horizontal member 10' of which project arms 21 having dovetailed -guidegrooves 211 formed in theirthead-p0rtions to receive the similarly shapedfheads 22on1' the rear ends of arms 23 connectedtogether:4 from their outcrfends by a horlzontal bar 24. The supplemental frame formed of these members 2?, 24 is reciprocably supported in the guides 21 by hingedlinks 25 connected with the arms 23 and'v Secured upon a spring-retracted rock-shaft 26 journaled in suitable bearings onthe framen10.l and provided onon'e endwithan-operatinghandle 2 7. Nozzles 28 of theshaperepre-A i sentedn-14`ig. 8 depend'rigidly-from the bar l 24 at,4 intervals corresponding with thosefbe:

The rotary solid plug of each valve is provided near its tapering end with a transverse passage 33 expanded -toward one end, as shown 1n Fig.

' 6, to communicate with an inlet-port 34 -in the underside of the valvecasing and with a cylinderLlling port,35 in the upper side of the same; land each plug is provided near its wider end with an arc-shaped passage 36 (Fig. 5) to communicate with an inlet-v port 37 for'compressed air in 'the' bottom of the casing'and with an air-pressure port 38 and an exhaustport 39 in the top of the casing. The spring-pressed stems of the plugs in the horizontal row of valves 3() are provided with handles 41 all connected together at their free ends by a handlebar 42, one end of which has pivotally connected with it an arm 43 extending from one end of a rock-shaft 431. journaled in a hearing 432 and carrying an operating handle 440m itsopposite end near which the shaft carries a forked stop 45 to bear at its ends alternately against the adjacent side of the frame 10 in turning the shaft 431 to limit the extent of turning it. Each valve-casing is surmounte'd by a measuring-cylinder 46 having an open base covering a filling-port 35, the cylinder containing a ipiston 47 on a stem 471 passing through a stu ng-boX in its upper end and alining with a threaded vertical stop-rod 48 adjustabl'y supported in bear'- ings 49, 50 projecting backwardlyfrom hori-i zontal ribs of the rear frame 101.

An airpressure pipe 51 leads from the upper end of each cylinder 46 to the port 38 in the valve-casing below it. The ports 34 of all the valve-casings in the row thereof vare connected by a pipe 52 forming a header and the ports 37 are similarly connected by an air-pressure conduit 53.

At 54 (Fig. 1) is represented a supplytank for liquid to be filled into bottles 17 This tank communicates from lits upper end through a supply-pipe 5 5 containing a shut o valve 56, with reservoir (not shown) for holding the supply 'ofthe liquid, and from its lower end through a pipe',5.7 Jand hoseextension 58 thereof with'thmrepen end of the header 52. A glass gageg is connected at its opposite ends, containing shutof valves 60 and 61, respectively, with the pipes 55 and 57. From an air-pressure' supply (not shown) there leads a pipe 62 containing a pressure-reducing valve 63 of any suitable or ordinary construction, one branch 64 of this pipe containinga shut-off valve 65 and leading into the tank 54 at its upper end, and the other branch 66 leading to the open end of the air-pressure conduit 53. A vent-pipe 67 extends from the pipe 64 and terminates in a pet-cock 68.

T-he machine` is operated as follows: The

- tank 54 being-charged through the pipe/55 to any desired' height with the liqu'i to be' filled 'into bottles, the vent-cock 68 being' meantime .open and the valve' 65 closed, air

' the ports 34, 35 of each with a valve-passage 33 and the ports 38,39 with a valvepassage 36, the' liquid forced into the header passes upward against the pistons 47 into the cylinders 46, whence the air in them vents through thepipes 51, ports 38, passages 36 and exhaust-ports 39. The stop-rods 48 are adj usted to be encountered by and arrest the rise of the piston-.rods at a predetermined height according to the extent of filling the cylinders. The charge admitted into cach cylinder is to be just su'flicient to fill a bottle 17 and the stop-rods are set in theirbearings to arrest the rise of the pistons when the cylinders are filled to that extent. If they are to be illeduniformly to discharge into and fill bottles of uniform capacity, all thev stop-rods are adjusted alike; but if bottles of different capacities. are to be filled the adjusted positions of the stop-rods vary accordingly. The operator then lowers the filling-tubes 29 through the necks of a transverse row of bottles, by turning the rockshaft 26 at the handle 27, and thereupon turns the handle 44 to rock the shaft 431L and thereby shift the handle-bar 42 to turn the plugs of all the valves to register their passages 36 with the respective ports 37 and 38 and their passages 33 with the respective ports 34 and lateral outlet-'passages 31 leading to the filling-tubes. Thus the air-pressure from the conduit 53 enters the cylinders 46 through the pipes 51 and exerts pressure upon the pistons tolower them and force the charge of liquid ahead of each through the respective valve-passages 33 and outlet-passage 31 into a bottle, into which the entire contents of a cylinder are thereby discharged. The operatbr then releases Vthe handle 27 to permit the sprillg-presiied rockshaft 26 to raise thefilling-tubes out of the bottles, and the handle 13" is turned, to cause the dogs 16 to shift the tray 19 in the direction for'bringing the next transverse row of bott-les into alinementl with the lling-tubes, whereupon the' latter are again lowered through the bottle-necks and the handle 44 is turned back to its initial position to permit the" pressure maintained in the tank 54 toagain charge the measurng Y cylinders, which are then discharged as and for the purpose already described. These operatlons are repeated for each row of bottles in as many trays thereof as the supplyv in the tank will suliice oreach tray, when the bottles it holds havebee'n filled, being )replaced by onefcontaining empty bottles.

stoppage of running when the measured quantity in a cyliiider is discharged, whether or not any or" the bottles be broken, and absence of packing and of telescoping tubes with their liability to get out of order and disorganize the machine.

What I claim as new and desire to secure by Letters Patent isl. In a iiilling machine of the character described, the combination'of a horizontal frame adapted to support a crate of pachages to be filled, an upright frame, filling valves supported on said upright frame, arms on the upright frame, a vertically movable supplemental frame guided on said arms, nozzles on said supplemental frame, filling tubes connected to said nozzles, iexible tubes connecting the nozzles with the filling valves, and means for operating said supplemental frame' to move the `filling tubes to and from filling position.

2. In a filling machine of the character described, the combination of a horizontal frame adapted to support a crate of packages to be filled, an upright frame, a plurality of measuring cylinders supported on the upright frame, a valve at the ylo ttom of each cylinder and having a plurality of ports and passages therein, a header connected to the supply holder for the material and to all the-valves,- another header connected to an air pressure supply and to all the valves, and means for operating all the lvalves simultaneously to admit the material to the cylinders and permit the a'ir therein to escape or to admit air under pressure to force the material out-of the cylinders.

3. In a -illing-machine 01EA the character described, the combination of a horizontal frame adapted to support a package to be filled, an upright-frame, a measuring cylinder supported onthe upright frame, a pistion in said cylinder, a multiple passage valve located at the bottom of the cylinder', air pressure supplying vmeans connected to said valve, and means for actuating said ,valve whereby to simultaneously admit material under pressure to the measuring cylinder below the piston and relieve the pressure above the piston, and to subsequently admit air under pressure to the cylinder above the piston and simultaneously relieve the pressure below the piston whereby the material will be discharged from the cylinder.
